23 Jul Biomedical electric activity water gel and preparation method thereof
Abstract
The invention discloses biomedical electric activity water gel and a preparation method thereof, and relates to the field of high molecular materials, in particular to the biomedical electric activitywater gel and the preparation method thereof. The biomedical electric activity water gel can be prepared by the method with steps of using natural and non-toxic compounds of glycine and choline to form ion liquid; then using acrylic acid to modify ion liquid; forming vinyl choline-glycine ion liquid monomers; using N, N-methylene bisacrylamide (MBAA) as crosslinking agents; using potassium peroxodisulfate (KPS) as initiators; preparing polyionic liquid gel through free radical polymerization; using the polyionic liquid gel as a first gel network; using American FDA authenticated polyethyleneglycol (PEG) as reaction monomers of a second gel network; using N, N-methylene bisacrylamide (MBAA) as the crosslinking agents; uisng potassium peroxodisulfate (KPS) as the initiators; forming the electric activity gel with the high mechanical strength with the first gel network. The gel has good biocompatibility and biodegradability and can be used in the fields of nerve tissue engineering, myocardiac tissue engineering and the like.
